SPECIFICATION forming part of Letters Patent No. 732,685, dated June 30,1903. Application filed September 17,1897. Serial No. 652,052. (Nomodel.) 4

To all whom it may concern:

Be it known that JAMES-J. JOHNSTON, de-

others skilled in the art to which it appertains to make and use thesame. j

This invention relates to gas-burners for burning gas made frompetroleum-oil or its distillates by forcing air through it, has for itsobject the construction of a burner that will produce a steady flamefree from. intermittent pulsations and that will prevent the possibilityof gas burning back into the supply-pipe, and'consistsin certainimprovements, which Will be fully disclosed in the followingspecification and claims.

In the accompanying drawings, which form part of this specification,Figure 1 represents a vertical longitudinal section of the burner; Fig.2, a vertical longitudinal section through a furnace provided with aburner, and Fig. 3 a front elevationof the same.

Reference being had to the drawings and the letters thereon, A indicatesthe burner, 13 the furnace, and C a boiler.

The burner consists of a hollow cylindrical body a, having areceiving-chamber 11 therein and provided with openings 0 c at each endand an opening (1 on its upper side, a hollow cylindrical body e, havinga distributingchamber f therein, and the two chambers b and f areconnected by a pipe g, which extends through the chamber 1), isscrew-threaded from a pointinside of the inner end of the body a to itsouter end and is provided with a series of perforations it within thereceiving-chamber and a cap a at its outer end.

The openings 0 c are smooth-bored, and the pipe 9 is secured in positionby nuts 7c k, with a packing Z Z interposed between them and the ends ofthe bosses m m. The openburner and also serve as asafeguard against thegas burning back into the source of supply. The perforations equal innumber the discharge-tubes n and are of the internal diameter of thetubes--na mely, one-fourth of an inch. a

The discharge-tubes n are about twelve inches long and are arranged in acircle in the inner head of the body 6.

The gas flowing from the receiving-chamher I) through pipe g intodistributing-cham berfexpan ds in the latter chamber,and thereby absorbsthe pulsations of the pump or from any other cause and produces a steadyand uninterrupted flow of gas to the tubes The burner is surrounded byan annular air-supplying chamber E, formed in the wall or masonry of thefurnace, and may be provided with a valve F, having a series of openingso to regulate the quantity of air admitted to supply oxygen to the gas.

The combustion-chamber G of the furnace is provided with perforated tile19, of refractory material, arranged at an angle to the plane of theburners and against which the gas from the burners and the air impingeas they enter the combustion-chamber. The tile becomes highly heated,and the gas and air, striking the inclined surface, enter theperforations, arethoroughly com mingled, and burn with great intensity.

Below the tile 13 is a chamber q, filled with pieces of fire-brick orother refractory material and into which the gas and the air on terthrough the perforations in the tile.

Having thus fully described the invention, what is claimed is- 1. Agas-burner provided with a receivingchamber, a distributing-chamberseparated from the receiving-chamber, a pipe extending through thereceiving-chamber, connecting with the distributing-chamber and providedwith perforations Within the receiving-chamher and a plurality ofdischarge-tubes com municating with the distributing-chamber.

2. A gas-burner provided with a receivingchamber having openings at'eachend and an 7 opening on one side, a distributing-chamber separate fromthe receiving-chamber, a pipe extending through the receiving-chamber,provided with perforations Within said chamher and connected to one endof the distributing-chamber, and discharge-tubes connected to theopposite end of the distributingchamber.

3. A gas-burner provided with a receivingchamber having a smooth-boredopening at each end and a screw-threaded opening on one side, asupply-pipe engaging said screwthreaded opening, a pipe externallyscrewthreaded extending through said chamber and provided withperforations within the chamber, means for securing the chamber to
